TOOL FOR APPLYING WIRE CLAMPS TO HOSE COUPLINGS.

Application filed January 21, 1924.

To all whom it may concern:

Be it known that I, FRED W. GUNN, a citizen of the United States, and resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Tools for Ap plying Wire Clamps to Hose Couplings, of which the following is'a specification.

My invention relates generally to improvements in tools for securing clamping or binding wires on a hose or like article, more particularlyto a tool which isparticularly well adapted for use in applying a wire clamp having the construction disclosed in my prior application for Letters Patent of the United States, Serial #661,419, filed September 7, 1923, and it consists in the combinations, constructions claimed.

An object of the invention is to provide a tool of the character described which is adapted to be easily and conveniently nianipulated to effect twisting together of the end portions of the clamping or binding wire against a length of hose or like article which is encircled by the binding or clamping wire and to then cause breaking off of the end ends of the twisted together portions thereof.

A further object of the invention is to provide a tool of the character described which affords facilities for twisting together end portions of a clamping wire so that the end portions of the clamping wire will be brok together portion and alsoat of the tool, thus facilitating removal of the broken off end portions of the wire from the tool.

elongated body 1 which preferably is enlarged adjacent one end thereof to provide a handle portion 2 which is adapted to be firmly gripped in the hand of the user. The

andle portion of the body is aperturcd as sake of lightness.

The body 1 is provided at its other end with a head 4 which is preferably circular in cross sectional contour and tapers toward its extremity, the end wall 5 of the head lying ina plane which extends at right angles to the longitudinal axis of the body. The head 4 extends laterally of one side of the body 1 and is provided with a bore 6 which extends longitudinally therethrough in parallel relation to the longitudinal axis of the body and at one side of the aforesaid side wall of the body.

The longitudinal axis of the body 1 is intersected by a transverse opening 7 which is formed in the body 1 a short distance rearwardly of the juncture of the body and head 4. A tightening pin 8 extends through the opening 7 and has an end portion 10 thereof protruding from one end of the opening 7 and located directly at the rear of the bore 6 in the head 4, the other end portion of the pin 8 protruding from the opposite end of the opening 7 and being enlarged and fashioned to be non-circular in cross sectional contour as indicated at 11 for a purpose to be hereinafter described. The tightening pin 8 is freely rotatable but is held against axial movement relatively to the body 1 by retaining pins 12 which are carried by the body and are ferentially extending groove 13 in the outer wall of the pin 8.

The tightening pin 8 has a diametrically extending slot 14 formedin the first mentioned end thereof. This slot preferably extends in'the pin to the planeof the adjacent face of the body 1.

An anchor pin 15 is secured adjacent to one end in a transverse opening 16 in the body 1 and extends laterally of the body 1 in spaced parallel relation to the tightening pin 8, being located rearwardly of the latter and at a slightly lower level.

The bore 6 is intersected adjacent its rearward end by a palr of vertically spaced parallel bores through the head 5 and which have the respective axes thereof located in planes equidistant from the axis of the bore 6. Each transverse bore 17 receives a spacing pin 18 partially received in a circumthe two pins 18 being spaced apart a distance which is just sufiiciently greater than the diameter of the wire of which a wire clamp is formed to permit the ends of the wire clamp to be inserted through the'bore G'between the guide pins, the distance between the two guide pins not being sufficiently great to permit the endportiofns of the clamp to be twisted together between the guide pins or rearwardly thereof.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The free ends of the wire clamp which'has been arranged in encircling relation to alength of hose or likearticle are extended through the bore 6 between the guide pins 18 in side by side relation andthen through the slot 14 in the'tightening pin 10 and finally are secured to the anchorpin 15 by having the extreme end portions thereoftwistedabout the anchor pin. At this time, the end of the head 5 will be in'position to clamp'orpress the wire clamp against the hoseor other article which is encircled by such wire clamp. As stated, the enlarged end portion 11 of the tightening pin 10 is non-circular in cross sectional con-tour and has a gsufficient number of faces to adaptit to be gripped-by a suitable wrench, or turning tool, not shown. The tightening pin 8 is turned by means of a wrench such asthatxmentioned until the wire clamp has been drawn tight. The body 1 then is "turned about its longitudinal axis, thus effecting the twisting of the end portions of the wire-clamp, whereby such clamp will be secured in place on a hose or like article. Since "the guide pins 18 prevent the twisting :together of the -end portions of the wire clamp between such guide pins or rearwardly thereof, :it will be manifest that continued turning of the body 1 about its longitudinal axis will cause the end portions of the wire clamp to be broken off between the guide pins 18. The broken off end of the wire clamp then may be removed readily from the tool.

Obviously, my invention is susceptible of embodiment in forms other than that illustrated in the accompanying drawing and I therefore consider as my own all such modifications and adaptations ofthe formof the device herein described as may fairly fall within the scope of the appended claims.

I claim:

1. A tool of the character described comprising an elongated body having a head at one end thereof, said headhaving a bore extending longitudinally therethrough, a pair of spaced apart guide members extending transversely through said bore, and a rotatable tightening pin carried :by said body, said tightening pin having a slotted .end portion extending at right angles to the direction of length of said bore and being located at the rear of saidihead. i

2. A tool of the character described comprising an elongated body havinga head at one end thereof, said'headhavi-ng a bore tending longitudinally therethrough, apair of spaced apart :guide members "extending transversely through said bore,and ea rotatable tightening pin carried by said body, said tightening pin having a slotted end portionvextending at right angles to the direction of length of said bore and being located at the rear of said head, and an anchor pin carried bysaidfbody, pin being located .rearwardly of said tightening pin and having a 'portion thereof disposed in spaced parallel relation to the slotted portion of said tighteningpin.

3. A tool of the character described comprising an elongated body havinga headat one end thereof, said head'having a bore extending longitudinally "therethrough, said bore being located laterally of the side of said body, a pair of spaced apart guidepins extending transversely through said bore adjacent to the rearward end of vthe latter, one of said guide ins'being disposed above the other, a rot-ata 'le-tightening .pincarried by said body, said tightening pin being located rearwardly ofsaid bead and having a slotted end portion extending laterally of said 'side of the body and at the rear of said bore, and an anchor pin carried by said body, said anchor pin being disposed rearwardly-of said tightening pin and :having a portion extending laterally of the may in spaced parallel relation to said tighten-.
